Injuries have forced two changes inSouth Africas squad for the T20 World Cup in India and Sri Lanka next month.

Batsman Tony de Zorzi and all-rounder Donovan Ferreira were both ruled out. They have been replaced by batsmen Ryan Rickelton and Tristan Stubbs ndash; who were both surprise omissions from the original squad.

Veteran batsman David Miller will miss a three-match series against the West Indies next week because of a groin injury and will need to pass a fitness test before joining the flight to India.

The left-handed De Zorzi, who has played in two T20 internationals, was a surprise choice when the original squad was announced three weeks ago.

De Zorzi suffered a hamstring injury in a one-day international in India last month. He missed the SA20 and according to a statement by Cricket South Africa has not progressed as expected in his rehabilitationrdquo;.

The hard-hitting Ferreira broke his collarbone in an SA20 match last week.

Rickelton was the leading run-scorer in the league phase of the SA20, which finishes on Saturday, while Stubbs was regarded as one of South Africas leading T20 players before suffering a dip in form last year.

Coach Shukri Conrad said he was optimistic that Miller would be able to recover in time.

He had a follow-up scan today and the results were positive, he said.

Left-handed batsman Rubin Hermann will replace Miller for the West Indies series, which starts in Paarl on Tuesday.
